Description

The present invention relates to a laminated mattress and a storage body including a plurality of mattresses, and more particularly to a laminated mattress and a storage body having a three-dimensional three-dimensional network made of synthetic resin as a main mattress.

  In recent years, a three-dimensional three-dimensional structure network in which the filaments made of polyester resin or polyethylene resin are irregularly curled or bent and the confounding points of each filament are fused at high temperatures is adjusted to a predetermined thickness. Various mattresses are commercially available. The three-dimensional three-dimensional structure network has an effect of better breathability, durability, and body pressure dispersibility than those using cotton or urethane foam, and also has a function (washability) that can be washed with water.

  The mattress of the three-dimensional three-dimensional structure network has been widely used because it has the above-mentioned functions. However, when actually used, the crispness of the cut surface of the synthetic resin and the hardness of the resin itself are unintentional to humans. In order to give a pleasant feeling, it is usually put in a bag instead of being naked, and further covered with a cover or the like.

  In addition, since the mattress of the three-dimensional three-dimensional structure network cannot be bent, the height of the person can be increased by dividing the mattress into a plurality of lengthwise directions in which a person lies down and arranging the divided mattresses in one direction. The length to cover is secured. However, as shown in FIG. 6, when a plurality of mattresses are connected so as to be folded using the individual bag 12, even if they are covered with the mattress cover 30, a portion corresponding to the refracting line at the time of folding, specifically There is a problem in that a slight space is generated at the boundary portion of b1 and b2 in FIG. 6, and the person feels subtle discomfort at the boundary portion, so that a comfortable sleeping feeling and a sense of security cannot be obtained.

  Patent Document 1 discloses an upper plate having a rectangular parallelepiped shape for the purpose of providing an assembly-type mattress that eliminates a problem in conveyance and reduces a sense of incongruity as much as possible with respect to a step generated between adjacent mat portions. An assembly-type mattress is disclosed that includes a mat, a flat rectangular parallelepiped undermat stacked below the mat, and a foldable mattress cover that can store the upper mat and the undermat in a stacked state.

  The upper mat and the under mat are composed of a plurality of mat pieces made of a cushioning material. The upper mat and the under mat are stacked, and the adjacent mat line of the upper mat mat pieces and the under mat mat are stacked. Since it is configured so that it does not overlap with the adjacent boundary line of one piece, the step generated at the boundary portion between adjacent mats is alleviated.

  In addition, if the upper mat is composed of a mat piece and edge mats applied to both the left and right sides of the mat piece, it will be difficult to displace due to the support of the edge mat, but the mattress cover will cause a sense of discomfort caused by the minute space generated in the adjacent part of the mat piece It was not possible to solve it by itself. Furthermore, not only is it very difficult to assemble and remove the mattress, but because the mattress material used is urethane, the functions such as the breathability and washability of the three-dimensional structure network described above are I don't have it.

It is sectional drawing of the other laminated structure mattress which concerns on this invention. It is a perspective view which shows the accommodation state which concerns on this invention. It is a perspective view of the structural member of the conventional laminated structure mattress.

(First embodiment)
Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a perspective view of a laminated mattress 1 according to the present invention, which is a flat rectangular parallelepiped. As shown in FIG. 1, the outer surface is covered with a mattress cover 30 and the end edge 30a is narrowed by an elastic body such as rubber. The side L1 is about 200 cm, the side L2 is about 100 cm, and the side L3 is about 14 cm.

  FIG. 2 is a cross-sectional view taken along line XX in FIG. 1. A laminated mattress 1 includes three lower mattresses 10 made of a synthetic resin three-dimensional structure network, and an upper mattress 20 made of urethane foam. , And a mattress cover 30 for covering them. Here, the reason why the three lower mattresses 10 are arranged is that the lower mattress 10 is made of a synthetic resin and therefore has a hardness of 130 N (N is measured according to Newton, JIS K6401). And it is divided into three in the direction that people sleep. The three lower mattresses 10 have the same size and the side L4 is about 67 cm.

  Further, as shown in FIG. 2, even when the two upper mattresses 10 are brought into close contact with each other, a boundary portion (adjacent portion) a is generated between them. For this reason, the boundary part a and other parts have different human touch. Therefore, the present invention eliminates the uncomfortable feeling by placing the upper mattress 20. The thickness d1 of the lower mattress 10 is about 9 cm, and the thickness d2 of the upper mattress 20 is about 5 cm. The reason why the thickness d2 of the upper mattress 20 is made thinner than the thickness d1 of the lower mattress 10 is as follows. This is to prevent the function of the three-dimensional three-dimensional structure network of 10 from being impaired.

  FIG. 3 is a perspective view of the components shown in FIG. 1, and each member will be described in detail. The three-dimensional three-dimensional structure network 10 made of a synthetic resin discharges a filament (filament) made of a resin made of polyester, polyethylene, ethylene vinyl acetate copolymer or the like into an atmosphere having a temperature higher than the melting point from a plurality of orifices. , Twist to form a random loop. Although the entangled portions where the random loops are in contact with each other are fused, the three-dimensional three-dimensional structure network 10 having a predetermined elasticity with a desired thickness can be obtained by immediately cooling in that state in water. At that time, various cross-sectional shapes can be produced depending on the shape of the orifice of the discharge device, but a wire-shaped solid type and a pipe-shaped hollow type can be exemplified. Such a three-dimensional three-dimensional network 10 realizes various functions such as good breathability, durability, body pressure dispersibility, and cleanability. For those who want hardness, a solid type is used. Examples of the three-dimensional three-dimensional network 10 include breath air (Toyobo Co., Ltd., registered trademark).

  Further, the upper mattress 20 can be made of wound cotton having a thickness of 2 to 5 cm, soft urethane foam, low-resilience urethane foam, or the like. In addition, when a thin mattress having the above-described three-dimensional three-dimensional structure network 10 is used as an upper mattress, a certain effect can be exhibited, but since the rigidity is too strong to be folded, packaging property and transportation Not appropriate in terms of sex. If priority is given to human touch, it is preferable to use a flexible urethane foam having a hardness of about 50 N (measured according to JIS K6401). Furthermore, in order to ensure breathability in addition to body sensibility, it is more preferable to use a flexible urethane foam that has been subjected to film-free treatment. Film-free treatment is to remove oil and other membranes in order to improve the breathability of flexible urethane foam, and methods for blasting injected oxygen and methods of drying after steam treatment are considered. . In addition, by performing film-free treatment, the breathability becomes 10 times or more (according to the Frazier-type breathability test) compared to coated products. As this film-free flexible urethane foam, Mumak (Achilles Corporation, Registered trademark).

  The material of the mattress cover 30 can be variously changed according to the season and preference, and as the material, cotton, polyester, a mixture of polyester and cotton, acrylic rayon, or the like can be used, and the edge 30a of the mattress cover. The bag is shaped like a rubber or string.

(Second embodiment)
FIG. 4 shows a cross-sectional view of the laminated mattress 2 in which the three-dimensional three-dimensional network 10 is put in an individual bag 12. The individual bag 12 is not easily soiled by using a nonwoven fabric made of polyethylene, polyester, polypropylene or the like. Further, by using the individual bag 12, the troublesome handling of the three-dimensional three-dimensional structure network 10 is eliminated, and the loading and unloading during assembly and storage is simplified.

  FIG. 5 shows a state where the laminated mattress 2 is stored in the storage body 40 in a folded state. The container 40 can be made of polyethylene, low-density polyethylene, polypropylene nonwoven fabric, or the like as a material, and can have a bag shape or a box shape. The upper mattress 20 is basically flexible, and the individual bag 30 is also folded, and the three-dimensional structure network 10 alone or the one in which the three-dimensional structure network 10 is put in the individual bag 12 is compact. Can be stored in a small space. As a result, since the total of the three sides of the storage body 40 is reduced, the transportation cost can be suppressed.

The content described above describes one mode for carrying out the invention, and is not limited to the above embodiment. For example, a 4-fold or 5-fold structure may be used for more compactness.
The present invention can be applied to various uses such as a bed, a sofa, a chair, and a pillow.
